GASKET.

- Specification of Letters. Patent.

pplication filed January 3. 1906. Serial No. 294,442.

`To all whom t may concern: Be. it known that I, JonN E. Sii'orr, acitizen ol" the United States, residing at Ganado, in the county ofJackson and State of Texas, have invented a new and useful Gasket, ofwhich the following is a specification. .This invention relates togaskets or packing-rings for pipe-joints and the like, and is moreparticularly an improvement upon another application filed by me in theUnited States Patent Office and bearing Serial No. 226,492.

Ordinarily gaskets and packing-rings are manufactured in standard sizes,and when making a connection if the workman-does not possess the propersize of gasket itis necessary to delay the Work Iuntil a gasket can beobtained from the shop. ln view of this difficulty it is the essentialobject of' the present invention to provide for the production ofgaskets by the Workman whenever desired without regard to the size andcharac* ter of the joint.

W'ith these and othery objects in view the present invention consists inthe combination and arrangement of parts hereinafter more fullydescribed, shown in the accom-v panying drawings, and particularlypointed out in the appended claim, it being Linden stood that changes inthe form, proportion, size; and ininor details may loe-'made within thescope of the claim without departing from the spirit or sacrificing anyof "the advantages of the invention.

In the drawings, Figure. 1 is a view of a length of material from whichone of the 'gaskets of the present invention is formed. Fig. 2 is asectional view of a pipe-cmipling having a gasket applied thereto inaccordance with the present invention, with the members of the jointinfreadiness to be Fig. 3 is a cross-sectional view of the joint withthe gasket in elevation prior to I Fig. 4 is a view similar to Fig. 2after the coupling members have been tightened and the gasket therebycompressed. Fig. 5 is a detail perspective view of the gasket beforebeing compressed. Fig. 6 is a detail perspective View ofthe gasket afterbeing compressed. Fig. 7 is a view of a modification. Fig. 8 is asectional view thereof preparatory to tightening the joint. Fig. 9 is asimilar viewi andswiveled thereon with its front endpcvfr# tion'vprojected beyond the coupling member showing the joint tightened andthe` Agasket j,

The

2 and internally threaded `to engage the. exi,

ternally-threaded portion of the .,coupligjr member 1.' As usual, thecoupling membl'j'fr,

2 hasa forwardly-directed?cylindrical flange 4, embracingthe to thereof,which; flange, is embraced by the adjacent end of the coupling member 1when the two members are assembled.-

ln carrying out they present4 iiiventiona suitable length' 5 of wire, asshown in Figni, is lcut" from a roll or spool vof Wire, and'this lengthof wire is wound a suitable number of times around the flange 4 of thecoupling member 2, as best indicated' in Fig. 3 of the drawings. Afterthe. gasket has thus been completed and fitted in place the couplinv"member 1v is associated with the s vviveled ring 3, and the latter isturned so as toldi'aiv the two coupling members together, and therebycompress the coils of the wireint'oa fiat' gasket, completely -lling thes' acefbetween the two coupling members, .t e flange 1i, and the ring 3.

ciently soft and pliable to enable the convenient severing of the sameand winding of the severed portion into a spiral gasket and also topermit of the contiguous coiled portions flowing into one another under'the compression incident to the tightening of the `joint. By preferencethe endsnof the Wire are severed obliquely in reversedire'ctions inorder that the inner coiled ortionnof the gasket may snugly hug the ange4 land in order that the outer end of the wire may merge into the outerface of the adjacent coil. The difference between Y the gasket prior tobein compresed and 'after being reference to Figs. 5 and 6, wherein 1twill` be j The Wire 5 slijouldbeyof .d leader any of its alloyspso as tobe suffi-4 noted that the initial vform of the gasket is that ofa spiral=with its individual spirals separated, but in successive contact, whilethe final form of thel gasket is that of a flat 5 single-piece ring,which is due to the fact that the spirals are com ressed between themembers of the'joint an are iiowed together A by the compression into asingle-piece washer.

The advantages of the present invention resides in the fact that it isnot necessary to depend upon a stock of gaskets, as a asket of any sizemay be quickly produce in a simple and effective manner, it being merelyt Ax 5 necessary to have on hand a reel or bundle of wire'from-Which[any suitable lengths may be cut in accordance with the sizeof the'desired gasket. By ithe present method of formingthe gasket the heavyexpense of zo maintaining -a stock of standard washers of :various sizesis eliminated, and the loss of ltime occasioned by-returning yto theshop for ,awasher is `obviated, Wherefore the present invention not onlyproduces an eiiective \Washer,but also-materiallyfreduceslthe ex? penseof carrying on the work of packincr pe-couplingsand similar characters o'joints Another arrangement of the present inven- A3o tion'fhasbeenShown inFigs. 7,8,and 9,

which discloses a' joint made up of a pair of -fduplicate collars-8and-9, having threaded Acircular opemngs receiving pipe-sections 10aridE-ll and also providedlwith"bolt-openings 3 5'y 12., -In tightening,this character of'- -joint the 'wireis wound a suitablenumber oftimesaround :the rpipewpening of the coupling --member 8, care being taken toyhave the -ini- -tial end orti'on Aagof44 the W-ire Vdis osedin 4o.substantially:tangential relation wit respect to.i ,the pipe-opening4and its extremity ladlja- "cent theouter ed e-of the, member 8. The-several'gwhirls :of t e wire pass over. the end l pontionf, and theoutermost 'whirl 5b passes around ati-the outer sides -fi the'bolt-.oen- '"i'ngs'Z beneath theze'nd portionj, an' vits textremiit 15V-ispushed under the several Whirlsf the gasket `inwardlyf toward i theIpipe-op'ening. Care should be taken to start 5o"thee1id'5 betweenoneof`the bolt-openings 12 and the pipeeopening, and the other` portion 5cshould pass around and thence inwardly at the other side of the samebolt, whereby the bolt-opening is embraced by the opposite ends of thegasket. Any approved form of bolts 13 are passed through the boltoenings, and suitable nuts 14 are fitted to t e bolts, so as to draw thecoupling members toward one another, and thereby compress the Wiregasket, as shown in Fig. 9, so aste 6o force adjacent whirls intoengagement vwith oneanother in the same manner as hereinbeforedescribed. By having the terminal 5 pass beneath the inner whirls andover the outer whirl, Withthe terminal 5n assed beneath the severalwhirls, the endso the gasket are interlocked with the whirls, andthereby yheld against looseness after the joint has been tightened. Tnthe embodiment shown in Figs. 7 8, and 9 `the coupling members are drawntoward lone another in a straight-line, andthereiore it is notnecessaryto coil the wire in any particular direction, whereas in Figs. 2, 3, and4 the coupling members are drawn toy ether by the action of a thread,and thereore it is preferred to coil the wire, -in the direction of thethreads. Should there be'any turning of either coupling member whentightening the same, the movement will be in the direction of the coilsof thel wire, which tends to hold the coils together rather than tospread them.

j Ha'vin Athus described the invention, what is claime is l pipe-jointor the like having an unconfned (wire -wound spirally between lthe memkvbers of the' joint, the 'outer whirl ofv the wire being expandedbetween the peripheries' of the members of' the joint, and means foryclamping the joint members uponthe wire to compress and spread it, theends of the -Wire :surrounding one of ysaid means and l overlapping.

'In testimony that I-claim the foregoing as my 4own l"l have heretoaffixed my signature 95 in the presence of two Witnesses.
